Item Evaluation of Colposcopy After the Addition of Human Papillomavirus Testing to the Turkish Cervical Cancer Screening Program(2023) Gunes, Ali Can; Ozgul, Nejat; Turkyilmaz, Murat; Kara, Fatih; Unlu, Fahriye; Ayhan, Ali; Gultekin, Murat; 37994572Objective: To evaluate colposcopy performance following the human papillomavirus (HPV) DNA screening program in Turkey. Methods: Women aged 30-65 years are screened for cervical cancer every 5 years, with individuals positive for HPV 16 and/or 18 or other high-risk HPV types with abnormal cytology referred for colposcopy. Both HPV test and cytology are obtained at the same visit. If HPV is negative, cytology will not be assessed. However, if HPV is positive, both cytology and HPV genotyping will be performed. Colposcopy-require was defined as HPV 16/18 positivity or abnormal smear results with any hrHPV positivity, and the remaining patients (normal smear with hrHPV positivity other than HPV 16/18) were grouped as colposcopy non-required. National data on colposcopy outcomes and unnecessary performance rates in February 2018-2019 were evaluated via a questionnaire. Results: A total of 9808 patients were included, divided based on colposcopy requirement: 5751 (58.6%) patients required colposcopy and 4057 (41.4%) did not. Unnecessary colposcopy was performed on 90.1% of the non-required group (3657 of 4057 patients). In the colposcopy-required group, 4455 patients (79.9%) underwent punch biopsy; 3194 (57.1%), endocervical curettage (ECC); and 421 (7.5%), "see and treat" in the non-required group, the results were 2790 (76.3%), 1957 (53.2%), and 211 (5.7%), respectively. A total of 746 cervical intraepithelial neoplasia (CIN)-3 isolates were detected, including 702 using existing screening and triage with 94.1% sensitivity (702/746). Multiple biopsies were taken in 69.8% (n = 3110) of patients from the colposcopy-required group and 63.7% (n = 1777) from the non-required group. The ECC samples included 19 cervical cancers and 212 >= CIN-3 lesions in the colposcopy-required group, and four cancers and 41 >= CIN-3 lesions in the non-required group. The proportion of >= CIN-3 lesions detected by ECC only was 4.7% (35 of 746 >= CIN-3 lesions). Conclusion: Our results showed high rates of unnecessary colposcopies, and a high percentage of multiple and random punch biopsies and ECC.Item Survival Associated with Extent of Radical Hysterectomy in Early-Stage Cervical Cancer: A Subanalysis of the Surveillance in Cervical Cancer (SCCAN) Collaborative Study(2023) Bizzarri, Nicolo; Querleu, Denis; Dostalek, Lukas; van Lonkhuijzen, Luc R. C. W.; Giannarelli, Diana; Lopez, Aldo; Salehi, Sahar; Ayhan, Ali; Kim, Sarah H.; Ortiz, David Isla; Klat, Jaroslav; Landoni, Fabio; Pareja, Rene; Manchanda, Ranjit; Kostun, Jan; Ramirez, Pedro T.; Meydanli, Mehmet M.; Odetto, Diego; Laky, Rene; Zapardiel, Ignacio; Weinberger, Vit; Dos Reis, Ricardo; Anchora, Luigi Pedone; Amaro, Karina; Akilli, Huseyin; Abu Rustum, Nadeem R.; Salcedo Hernandez, Rosa A.; Javurkova, Veronika; Mom, Constantijne H.; Scambia, Giovanni; Falconer, Henrik; Cibula, David; 37336255BACKGROUND: International guidelines recommend tailoring the radicality of hysterectomy according to the known preoperative tumor characteristics in patients with early-stage cervical cancer.OBJECTIVE: This study aimed to assess whether increased radicality had an effect on 5-year disease-free survival in patients with early-stage cervical cancer undergoing radical hysterectomy. The secondary aims were 5-year overall survival and pattern of recurrence.STUDY DESIGN: This was an international, multicenter, retrospective study from the Surveillance in Cervical CANcer (SCCAN) collaborative cohort. Patients with the International Federation of Gynecology and Obstetrics 2009 stage IB1 and IIA1 who underwent open type B/C1/C2 radical hysterectomy according to Querleu-Morrow classification between January 2007 and December 2016, who did not undergo neoadjuvant chemotherapy and who had negative lymph nodes and free surgical margins at final histology, were included. Descriptive statistics and survival analyses were performed. Patients were stratified according to pathologic tumor diameter. Propensity score match analysis was performed to balance baseline characteristics in patients undergoing nerve-sparing and non-nerve-sparing radical hysterectomy.RESULTS: A total of 1257 patients were included. Of note, 883 patients (70.2%) underwent nerve-sparing radical hysterectomy, and 374 patients (29.8%) underwent non-nerve-sparing radical hysterectomy. Baseline differences between the study groups were found for tumor stage and diameter (higher use of non-nerve-sparing radical hysterectomy for tumors >2 cm or with vaginal involvement; P<.0001). The use of adjuvant therapy in patients undergoing nerve-sparing and non-nerve-sparing radical hysterectomy was 27.3% vs 28.6%, respectively (P=.63). Five-year disease-free survival in patients undergoing nerve-sparing vs non-nerve-sparing radical hysterectomy was 90.1% (95% confidence interval, 87.9-92.2) vs 93.8% (95% confidence interval, 91.1-96.5), respectively (P=.047). Non-nerve-sparing radical hysterectomy was independently associated with better disease-free survival at multivariable analysis performed on the entire cohort (hazard ratio, 0.50; 95% confidence interval, 0.31-0.81; P=.004). Furthermore, 5-year overall survival in patients undergoing nerve-sparing vs non-nerve-sparing radical hysterectomy was 95.7% (95% confidence interval, 94.1-97.2) vs non-nerve-sparing 96.5% (95% confidence interval, 94.3-98.7), respectively (P=.78). In patients with a tumor diameter <= 20 mm, 5-year disease-free survival was 94.7% in nerve-sparing radical hysterectomy vs 96.2% in non-nerve-sparing radical hysterectomy (P=.22). In patients with tumors between 21 and 40 mm, 5-year disease-free survival was 90.3% in non-nerve-sparing radical hysterectomy vs 83.1% in nerve sparing radical hysterectomy (P=.016) (no significant difference in the rate of adjuvant treatment in this subgroup, P=.47). This was confirmed after propensity match score analysis (balancing the 2 study groups). The pattern of recurrence in the propensity-matched population did not demonstrate any difference (P=.70).CONCLUSION: For tumors <= 20 mm, no survival difference was found with more radical hysterectomy. For tumors between 21 and 40 mm, a more radical hysterectomy was associated with improved 5-year disease free survival. No difference in the pattern of recurrence according to the extent of radicality was observed. Non-nerve-sparing radical hysterectomy was associated with better 5-year disease-free survival than nerve sparing radical hysterectomy after propensity score match analysis.Item Cisplatin Plus Paclitaxel And Bevacizumab Versus Carboplatin Plus Paclitaxel And Bevacizumab For The First-Line Treatment Of Metastatic Or Recurrent Cervical Cancer(2022) Ilhan, Yusuf; Tatli, Ali Murat; Teker, Fatih; Onder, Arif Hakan; Kose, Fatih; Geredeli, Caglayan; Karaagac, Mustafa; Kaplan, Muhammet Ali; Inanc, Mevlude; Aydin, Sabin Goktas; Kargi, Aysegul; Arak, Haci; Ozturk, Banu; Besen, Ali Ayberk; Selvi, Oguzhan; Korkmaz, Mustafa; Oruc, Zeynep; Bozkurt, Oktay; Bilici, Ahmet; Bayram, Selami; Dae, Shute Ailia; Ozdogan, Mustafa; Coskun, Hasan Senol; Goksu, Sema Sezgin; 35086927Objective Cisplatin-paclitaxel and bevacizumab is a frequently used treatment regimen for metastatic or recurrent cervical cancer, and carboplatin-paclitaxel and bevacizumab are also among the recommended regimens. In this study we aimed to evaluate the efficacy of these two regimens for the treatment of metastatic or recurrent cervical cancer. Methods Patients with metastatic or recurrent cervical cancer treated with cisplatin-paclitaxel and bevacizumab or carboplatin-paclitaxel and bevacizumab were retrospectively evaluated in this study. The clinical and demographic characteristics of patients in each group were evaluated. Median overall survival, progression-free survival, and response rates between the two groups were compared. Results A total of 250 patients were included. Overall, the numbers of patients with recurrent disease and metastatic disease were 159 and 91, respectively. The most common histologic subtype was squamous cell carcinoma (83.2%). The median duration of follow-up was 13.6 (range 0.5-86) months. The median progression-free survival was 10.5 (95% CI 9.0 to 11.8) months in the cisplatin-paclitaxel and bevacizumab group (group 1), and 10.8 (95% CI 8.6 to 13.0) months in the carboplatin-paclitaxel and bevacizumab group (group 2) (HR 1.20; 95% CI 0.88 to 1.63; p=0.25). The median overall survival was 19.1 (95% CI 13.0 to 25.1) months in group 1 and 18.3 (95% CI 15.3 to 21.3) months in group 2 (HR 1.28; 95% CI 0.91 to 1.80; p=0.15). Conclusions There is no survival difference between cisplatin or carboplatin combined with paclitaxel and bevacizumab in metastatic or recurrent cervical cancer.Item Oncological and obstetric outcomes after fertility-sparing radical abdominal trachelectomy for early stage cervical cancer: a tertiary centre's 10 years' experience(2019) Ayhan, Ali; Tohma, Yusuf Aytac; Sahin, Hanifi; Kocaman, Eda; Tunc, Mehmet; Haberal, Asuman Nihan; 0000-0001-9418-4733; 30371139; AAE-6482-2021The aim of this study is to present our clinical experience about fertility-sparing procedures in early stage cervical cancer and its obstetrical and oncological outcomes. Between the years 2006 and 2016, a total of 22 early stage cervical cancer patients who underwent a fertility-sparing radical abdominal trachelectomy in our clinic were retrospectively analysed. The median age was 33 (range: 28-39) years. The median follow-up was 47 (range: 22-125) months. Five patients (22.7%) had Stage IA1, three patients had (13.6%) Stage IA2, and 14 patients (63.6%) had Stage IB1 disease. Only one patient had a recurrence. A pregnancy was obtained in five patients (22.7%) and one of them (20%) had a live birth. A pregnancy was obtained spontaneously in two patients (40%), whereas assisted reproductive techniques were used in three of the patients (60%). A miscarriage occurred in two patients (40%), and one of them was within the first trimester and the other was within the second trimester.
